LTC3407EMSE-2#TRPBF - Dual Synchronous Step-Down Regulator

The LTC3407EMSE-2#TRPBF is a high-efficiency, dual-channel, synchronous step-down voltage regulator produced by Linear Technology, now part of Analog Devices. This compact and versatile regulator is designed to minimize external component count while providing optimal performance for portable devices that require dual power supplies.

Key Features:

• Wide Input Voltage Range: The device operates from an input voltage range of 2.5V to 5.5V, making it suitable for single Li-Ion, multi-cell alkaline, or NiMH applications, as well as for 3.3V or 5V input rails.
• Dual 600mA Outputs: It is capable of delivering up to 600mA of continuous output current from each channel, which can satisfy the power requirements of various applications, including PDAs, portable media players, and other handheld devices.
• High Efficiency: The LTC3407EMSE-2#TRPBF utilizes a constant-frequency, current mode architecture, along with internal synchronous rectification, to achieve high efficiencies of up to 96%.
• Adjustable Switching Frequency: The switching frequency can be programmed up to 4MHz, allowing the use of small, low-cost capacitors and inductors while also providing fast transient response.
• Low Dropout Operation: The low RDS(ON) internal switches enable low dropout operation, which extends battery life by allowing the regulator to maintain a regulated output even when the input voltage is close to the output voltage.
• Independent Shutdown and Soft-Start: Each channel can be independently shut down, and soft-start capability is integrated to control inrush current during startup.
• Thermal Protection: The device includes over-temperature protection to safeguard the regulator under high-load conditions and thermal stress.
• Compact Package: It comes in a 10-lead MSOP package, which is ideal for space-constrained applications.

Applications:

The LTC3407EMSE-2#TRPBF is well-suited for powering portable devices where dual power supplies are needed, such as handheld medical devices, GPS receivers, and other battery-operated consumer electronics. Its high efficiency and small footprint make it an excellent choice for designers looking to optimize power management in compact, battery-dependent applications.

With its robust feature set and Linear Technology's reputation for quality, the LTC3407EMSE-2#TRPBF is a reliable and efficient solution for your dual-channel power supply needs.
